<u>Answer:</u> The internal energy change for the reaction is -2850 J
<u>Explanation:</u>
- <u>Sign convention of heat:</u>
When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.
- <u>Sign convention of work:</u>
Work done for expansion process is taken as negative and work done for compression is taken as positive.
According to the First law of thermodynamics,

where,
= internal energy
q = heat absorbed or released = -2290 J
w = work done = -560 J
Putting values in above equation, we get:

Hence, the internal energy change for the reaction is -2850 J
